Chapter 216 Example Questions

"With chlorine and hydrochloric acid, I found that I could heat the sludge obtained near the platinum to produce partial dissolution by setting up a glass test equipment."

"Then the burning coke passes into the water vapor, which can get a harsh and pungent gas, which can make the clear hydrochloric acid platinum solution produce precipitation, and then melt this precipitation with a crucible furnace, ah no, according to your statement, it should be called reduction, hehehe, you get this."

Su You was dumbfounded: "Hehe, hehehe...... Manganese dioxide is added to hydrochloric acid to obtain chlorine, and coke water vapor method is used to obtain ammonia...... Platinum group extraction by solution extraction...... Hehehe...... Brother, why haven't you gone to heaven yet...... Do you know Nobel? ”

Zhang Xiangzhong felt very strange: "Luo Beier? It sounds like the stage name of a famous prostitute. Brother, I am obsessed with Dan Dao, how can I be robbed of my Dao heart by an ordinary woman? The thrill of discovering a new substance is no worse than that of a woman! Hi you're still a kid, I can't tell you about this......"

Su You touched the cold sweat on his head: "I don't mean that my brother is so terrifying, so what, give me a ring......"

Zhang Xiangzhong lit an alcohol blowtorch: "The ring is used for fart, show you a trick for my brother." ”

The blowtorch burst into flames, and Zhang Xiangzhong took a filament cover and covered it, and the wire immediately emitted a strong and dazzling white light.

Zhang Xiangzhong took a glass protective lampshade and looked at Su You's ghost-like expression with satisfaction: "In order not to let the virtuous brother specialize in beauty, I also designed a blowtorch for my brother, which does not need to be replaced every time the asbestos gauze cover, and it is not easy to break, it is more durable and beautiful than your blowtorch, how about it?" ”

Su You was reluctant to admit that he lost to the ancients: "No, no, no, your lamp is too expensive, mine is cheap." ”

Zhang Xiangzhong scoffed: "People who can afford to burn half a pound of alcohol every night, do you think they will care about this?" I don't care anyway......"

"Besides, this thing is treated as silver by everyone, and it is much cheaper than your asbestos gauze."

Su You continued to deny: "You are difficult to refine this metal......

Zhang Xiangzhong said: "Its practical natural platinum smelting and drawing is the same, the reason why I want to be so troublesome is just to purify the metal and research." And after more than 20 times of filtration, I found that the three batches of precipitation before, during and after the precipitation, the metal density obtained is different, I can't imagine that it is more than two different metals, and I am still researching, well, still researching......"

Su You finally surrendered: "Don't want anything else, this wire mesh, I will collect as much as I want, the price of silver, right?" I'm out twice, no, three times! ”

Zhang Xiangzhong laughed and said, "Do you think your brother is like a person who is poor in money?" ”

After speaking, he extinguished the alcohol lamp: "A speculum mirror, a tael of platinum." ”

Su You jumped up: "You knock on my bamboo pole!" You're picking this thing! ”

Zhang Xiangzhong nodded: "Yes, but I don't have you." When you sold us Yongchun dew, didn't you educate me not to disturb the market? Say that even if it is gold kicked out, it is gold and cannot be sold at the price of brass? ”

"Lean on ......" Su You stretched out two fingers: "Two two!" ”

Zhang Xiangzhong said with a smile: "Deal!" ”

Both foxes were secretly smug in their hearts.

What Zhang Xiangzhong thought was that the Heavenly Master Dao had created the Dao for thousands of years, and for the sake of the Mithril technique, he had collected a lot of these things, and used these useless things to exchange two or two for a peep mirror, and the Heavenly Master Dao took the peeping mirror to the various avenues to brush up on the prestige, which was a flat trip!

Su You thought that this brother is still stupid, my alcohol blowtorch uses asbestos netting, you use platinum mesh, but you only need a platinum thin spring filament, so it's a pure waste.

A platinum wire or two can make a lot of incandescent lamps......

Both of them were very satisfied, looked at each other, saluted each other, brothers and friends, and were full of affection.

Coming out of the inner room, Su Youcai said: "Brother is wise and researches the sky, and the foolish brother can only be admired." In the future, if there is any need to manage and put forward by yourself, even if the foolish brother can't solve it, everyone will learn together, and it will be beneficial. ”

Zhang Xiangzhong said: "With the help of my virtuous brother, many things are like clouds and mist dispersing, and there is no other way." Now the fellow Daoists are studying Liezi's theory, and Qin Tianjian is also making observations, or he may soon make a discovery. ”

Su You smiled: "It's good not to think that the telescope is a monster." ”

Zhang Xiangzhong said with a smile: "The truth is analyzed transparently, and there are diagrams, if you can't understand it, it's called a fool, not the elite of my avenue, and the master of Qintian." ”

Su You bowed: "I'm here to observe surface ships, you want to take it to see the stars and the moon, and it's none of my business to fight for the dog's brain in the future." ”

Zhang Xiangzhong couldn't help laughing: "You, if you are really like your name!" ”

came out to announce his speech to Whitebeard, and made an appointment to appreciate his slow swallowing swordsmanship and the medicinal powder prepared by Sanqi another day, and Su You led Wei'er out of the door of the jade game.

Xue Zhong stayed at the door and sent the two of them to the car.

After passing through the Qingyang Shop and entering the city gate, the carriage headed towards the inner city.

Su You lifted the curtain and talked with Shi Wei on the window watching the excitement.

The inner city of Chengdu is square, the outer city is the gossip type, and the person who built the city was Zhang Yi first, and then Zhuge Liang. Both of them are figures who have a lot to do with Taoism, and the whole city is full of philosophical charm.

Chengdu has always been leisurely, lively and lively, but even the voice of the hawkers is full of a lazy taste.

Many nobles sat on something like a bed, with pillars and curtains at the four corners, and were carried by people to go shopping.

Su You looked surprised: "Vier Weier, what kind of weirdness is that?" ”

Shi Wei said: "It's just that, it's so weird, I heard that it's called a bed." It is a noble person who travels and rides. ”

Xue Zhong said with a smile: "There is also a business name for this thing, it is much more exquisite than this, if Engong likes it, I will order someone to get it tomorrow and give Engong and Xianqing little lady a play." ”

Su You thought that he and Wei'er slept in the same bed, and then were carried around by four people to parade through the street, and the people around were curious and watched, and couldn't help but shudder: "Don't don't, just prepare two horses for us." ”

Xue Zhong said with a smile: "Chengdu people like this, wait for April 8th, you see, when the time comes, Bachelor Zhang's big bed will be the leader, and behind will be the deputy envoy, the general judge, and then the small bed of countless gentry will follow." All the way to the riverside, that is called a lively, this is called swimming. ”

Su oil is a bit dizzy - if the origin of this word is here, it is not a good word.

When he came to the transfer office, Xue Zhong stepped forward to report, and Zhike led the three of them into the door.

The yamen occupies a wide area, but the houses are dilapidated, and the officials do not repair the yamen, which seems to have started from now on.

When I came to the study, I listened to the conversation and laughter inside, as if I was commenting on the test papers.

I heard a voice laugh and said: "I just said that Bashu has been a great sage since ancient times, and now it is lonely?" Don't say that there is no one in Shu, there are people in Shu! Hahahaha...... Ming Yun, the second son of the Ru family, is not a thing in the pool. ”

I heard Su Xun say: "Ming Gong's words are serious, or they are considerable, and you have to ask Ming Gong to supervise one or two." ”

The voice was Zhang Fangping: "Genius, all genius!" The elder Ming Min is especially cute. However, the young are cautious, and their future achievements may be higher than those of the elderly. ”

Su You came in and saw Su Shi and Su Xun standing on the side trembling, while Su Xun and an old man in regular clothes were sitting and talking.

The old man had a thin face, a large figure, wearing a silk robe and a square gauze crown on his head, and saw Su You come in: "This is the one in your family who can wait and come out of his own way'?" ”

Su Xun said with a smile: "Ming Gong is laughing, this is the younger brother Su You." The one next to her is the little lady of the Shi family. ”

Su You led Shi Wei forward: "Su You brought Shi Wei and saw Ming Gong, don't blame me for being late." ”

The old man was Zhang Fangping, and said with a smile: "No blame, no blame, there is a test paper on the table, you can do it." ”

"Huh?"

Zhang Fangping said with a smile: "I deliberately came so late, I'm afraid that I have the intention of avoiding the school, and I really don't understand the old man?" ”

Su Shi secretly made a gesture of three, which is an old trick used in the family exam of the three uncles and nephews, which means third-class difficulty.

The third-class difficulty is incredible, the Su family is third-class, that is the level of the middle test.

Su You had no choice but to go over hard, and when he looked at the test questions, he couldn't help laughing, and arched his hand: "Ming Gong, please ask for another question." ”

Zhang Fangping was a little surprised: "Oh? How simple is this question for you? ”

Su You touched his nose and said embarrassedly: "This is the type of question that is explained on weekdays in the Land Temple Primary School, I call it an example question, which is mainly used to inspire everyone's interest, and the characteristic is that the calculation is very simple, mainly used for analyzing ideas." ”

This is an old question.

There are things that are not numbered today,

Two of the threes,

Three out of five,

Two of the sevens,

Ask about the geometry of things?
